Why .999... != 1 ( why .99999999999... does not equal 1 )
Algebraic Disproof Above is the correct breakdown, and below is how the proponent of .999... = 1 believes he's proved his theory: notice he makes an odd jump of from Step 2 to Step 3.

A problem I see is with the algebraic equation in the proponent's Step 3, written as 9c = 9. This is incorrect. It should be 9 = 9. Step 1 is: (10 * c) - c = 9.999.. - c; So we process (10 * c), resulting in 9.999... and then removed c from both sides of the equation, leaving 9 = 9, not 9c = 9. Well, you can do this with any variable, like this: 10x = 40. 10x - x = 40 - x. 36 = 36. 36/36 = 36/36. x doesn't equal 1, x = 4. Nor is c equal to 1, c = .999...

If you want further proof that .999... != 1, try getting 1 to equal .999... hah = ) The con was great fun though, thanks  = )
